FIRE-BOX FOR FIREPLACES.

SPECIFICATION forming part of Letters Patent N 0. 735,532, dated August 4, 1903.

Applicationfiled September 12, 1902. Serial No. 123,092.

In the constructional form shown in Figs. The fireplace acts in the following manner: 1 to 5, ct is the stove-drum, having in front a During combustion the cylinder is made to large openingb, and above this one aguard c. assume the position shown in Fig. 1 when Inside the drum a is arranged a cylindricallythe aperture t' of the cylinder is just above curved draft-grate f, provided with openings the grate d, which then forms the bottom of I00 6, and which extends upward in front of the the fire-chamber. If fresh fuel is to be introlower part of the opening b.

This latter willwhen the cylinder has been turned about one hundred and eighty degrees again form the bottom of the fire-chamber,the aperture being then above thegrated. (See Fig.2.) The fresh fuelis then introduced and the coveru closed,where upon the cylinder 9 is again turned about one hundred and eighty degrees by means of the rod 4. During this turning of the cylinder its contents will also be carried around,as the unevennesses of the cylinder, the edge of the plate n, with lining m, and the projections 'r s will serve as carriers for the fuel. A turning of about one hundred and eighty degrees will thus turn the contents of the cylinder upside down, so that the glowing embers are now on top of the fresh fuel. During the introduction of the fresh fuel the inomentaneouslydeveloped smoke will pass to the chimney between the edge of the cover it and the guard c, the cover it being opened and the plate so being simultaneously lowered to the position shown in Fig. 2. When the cover n. is shut, the plate a: will be raised, and the smoke can now pass out through the opening '7 between the plate wand the stop y. When the cover it is but partly open, the plate 00 but partly closes the opening 7, and it will consequently be possible to regulate the draft simply by opening the cover it more or less. If it be desired to obtain a brisk draft, the cylinder maybe turned from the position shown in Fig. 1 in the direction opposite to that indicated by the arrow 6, so that the aperture icomes in front of the grate fand that the grate d is closed by the plate n. The air will then pass in through the holes e of the grate f, and, owing to the increased draft thus produced, the ignition of the fuel will rapidly increase in intensity. In order to effect a turning of the cylinder in the direction opposite to that of the arrow 6, the arm 4 is provided with a pawl 8, which by means of a rod 9 and a handle 10 can be made to gear with a tooth-wheel ll, mounted alongside the tooth-wheel 5, the pawl 3 being simultaneously brought out of gear.

As it may happen during the turning of the cylinder that pieces of fuel may drop out through the holes q and be squeezed in between the gratesfand 2), whereby the turning of the cylinder will be rendered difiicult, the grates d andf, which are in rigid connection with each other, are mounted in a movable manner. To this end the connected grates d andf besides resting upon the fixed bolt 12 are further supported by a pin 13, capable of moving in a slot in the side plate of the stove, and which is secured to a lever 15, that carries a counterweight 16 and turns on a pin 14 on the side plate.

By turning the cylinder 9 very little to the one or the other side the holes e and q may be caused to be covered partly by the plates draft-grate may be regulated as desired.

In the constructional form of the invention shown in Fig. 6 the grate d and the cover to are mounted movably in grooves in the end walls of the cylinder. By suitably moving the grate (l or the cover it the draft through the grate p or the outlet to the chimney may be regulated. In other respects the fireplace acts in the same manner as that shown in Figs. 1 to 5.

In the constructional form shown in Fig. 7 the cylinder 9 is a fixture and is provided at the bottom with a grate 18 and at the top with a feeding-opening k, which can be closed by the cover it. Inside the cylinder is arranged a wing 1.), which can be turned by'a suitable handle from the outside.

\Vhen it is desired to introduce fresh fuel, the wing 1.) has to be turned in the direction indicated by the arrow 20. The wing will then push the glowing embers away from the grate 18 and carry them upward until the wing is stopped, which takes place shortly before it reaches the position shown in Fig. 7. The fresh fuel is now thrown in, whereupon the Wing is turned farther in the direction indicated by the arrow 20. Owing to this turning the glowing embers resting upon the wing will slide down and be spread over the fresh fuel.

In lieu of the container being made of a cylindrical form it maybe made prismatical or spherical.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A fireplace of the kind described, comprising a container for fuel, consisting of a horizontally-mounted rotating cylinder having two large openings and draft-openings between the first-named openings, projections in the cylinder operating to cause the fuel to partake of a rotary movement with the cylinder, and a swinging cover for one of said large openings, substantially as specified.

2. In a fireplace, or the like, a cylindrical rotary fuel-holder having opposite openings and draft-openings, a fixed grate below the holder and a prolongation for said'grate, and having openings for regulating said draftopenings, substantially as specified.

3. In a fireplace, or the like, a rotary fuelholder having inwardly-projecting teeth, the said holder also having opposite openings, a swinging cover for one of the openings, a deflecting-plate pivoted to said cover, and rollers on which said plate moves, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
